AP Exhaust: Nearly a Century of Exhaust & Emissions Excellence
AP Emissions Technologies has been at the forefront of the automotive exhaust and emissions aftermarket since 1927. Founded originally as Goerlich's, Inc., the company's roots reach back to the very beginnings of the automotive exhaust system business — a heritage that spans nearly a century of engineering innovation. Today, headquartered in Goldsboro, North Carolina, AP Emissions is recognized as one of the industry's leading manufacturers and suppliers of exhaust and emissions products for passenger cars, light trucks, and heavy-duty commercial vehicles.
What sets AP Emissions apart is its commitment to vertical integration. The company manufactures the vast majority of its components in-house — from raw steel coils through finished assemblies — giving it precise control over quality at every stage of production. This approach means AP can respond rapidly to market demands and ensure that every part meets or exceeds original equipment specifications. Constant research and development has yielded numerous patented designs over the years, including the patented Single Cartridge Internal Muffler, which delivers improved performance and longevity compared to conventional designs.
AP's product catalog covers the full spectrum of undercar exhaust needs. The brand's catalytic converters are available in both direct-fit and universal configurations, engineered to meet EPA and CARB emissions standards. For the structural backbone of any exhaust system, AP's exhaust pipes are produced using both mandrel and compression bending techniques — with mandrel bending preserving the full internal diameter of the tube to maximize exhaust flow and minimize back pressure. Completing the system, the brand's exhaust tail pipes are built from high-quality aluminized and stainless steel for durability and corrosion resistance.
AP Emissions also offers a comprehensive range of muffler products for virtually every application. Whether a technician needs a bolt-on exhaust muffler assembly for a straightforward OE replacement or an individual exhaust muffler for a custom installation, AP has solutions designed to match original fit and function. The brand's muffler lineup covers everything from quiet, OE-style replacements to performance-oriented options that improve exhaust flow without dramatically changing a vehicle's sound character.
With multiple manufacturing facilities across the eastern United States, a catalog spanning thousands of domestic and import applications, and a deep history of serving professional technicians and commercial customers, AP Emissions Technologies remains one of the most trusted names in the exhaust and emissions aftermarket — a legacy earned one precisely engineered part at a time.
